Figure 7

MRI images and MRI index of different groups. (a) Typical T2-weighted MRI images of different groups preoperation, preinjection, and 1, 2, 4, and 8 weeks after injection. (b) The MRI index was applied to quantitatively evaluate the rehydration and regeneration of degenerative disc. The H-gel+cell group is the hydrogel+cell group. All data are expressed as the ; the error bars represent the standard deviation of measurements for 6 separate samples (); , compared with control group; , compared with hydrogel+cell group; , compared with cell group.
